[PATCH] hexagon: make arch_spin_trylock() return signed int

[Rolf Eike Beer <eb@emlix.com>]

In contrast to all other architectures this was using an unsigned int while the
variable used to hold the return value inside the function is signed as well.

Not tested in any way, but what could possibly go wrong when fiddling with low
level locking? ;)
